1.
[src/sys/arch/arm/nvidia/tegra_xusb.c:214] -> [src/sys/arch/arm/nvidia/tegra_xusb.c:216]: (style) Variable 'error' is reassigned a value before the old one has been used.

Source code is

    error = clk_set_rate(clk, 102000000);
    rate = clk_get_rate(clk);
    error = clk_enable(clk); /* XXX set frequency */
    device_printf(sc->sc_dev, "rate %u error %d\n", rate, error);

    error = clk_set_rate(clk, 204000000);
    rate = clk_get_rate(clk);
    error = clk_enable(clk);
    device_printf(sc->sc_dev, "rate %u error %d\n", rate, error);
